1. Rack-and-pinion Petrol Car steering gear: It is the most common type of Petrol Car steering gear. Its basic structure is a pair of pinions and racks meshing with each other. When the steering shaft drives the pinions to rotate, the racks and pinions move in a straight line. sports.
2. Worm crank Petrol Car steering gear: a Petrol Car steering gear with the worm as the active component and the crank pin as the driven component. The worm has a trapezoidal thread, and a finger-cone finger-pin bearing is supported on the crank. The crank and the steering rocker arm shaft form an integral body. When turning, use the steering wheel to turn the worm. The tapered pin embedded in the worm groove rotates on one side and moves in an arc around the axis of the rotating arm to drive the crank and the vertical arm to swing, and then rotates the wheel through the rotating transmission mechanism.
3. Recirculating ball Geely Car steering gear: recirculating ball power steering system. The main structure consists of mechanical and hydraulic parts
The mechanical part is composed of shell, side cover, upper cover, lower cover, circulating ball screw, rack nut, rotary valve core and sector gear shaft. There are two pairs of transmission pairs: one pair is screws and screw nuts, and the other pair is rack, tooth sector or sector pinion shaft. A cyclically rolling steel ball is installed between the screw and the rack nut to convert sliding friction into rolling friction, thereby improving transmission efficiency.
